Unit test: footnote.005

Papers typically start on an odd-numbered, right-hand page: this could just follow from right-hand pages being the ‘front’ of a leaf, or it could be a by-product of single-article reprints of papers needing to start on a right-hand page.¹ Graphics are typically floated to the top (and sometimes also to the bottom) of the page. In a two-column paper, graphics can be either one column wide or span both columns. Large graphics might instead be grouped at the back of the paper, after the references. The combination of a two-column layout plus floating figures generally takes fewer pages than if all text, headings, and figures span the width of the page.
